SPECIFICATION forming 'part of Letters Patent No. 294,643, dated March 4, 1884.

v l Application filed July 2, 1883. (No model.) 'I i U To a/ZZ whom iv' may concern:

Beit known that I, CHARLES S. LEWIS, of metal, suchas iron.

Waterbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Pull Knobs or Handles,of which the following is a specifi cation. l l

'Ihis improvement relates, particularly, to knobs or handles which are designed for use on stoves. i

The object of the improvement is to pro-- duce a simple, cheap, and strong knob Orhandle Which will be adapted tovsuch use. Y

To this end the improvement consists in the combination, with a shell of sheet metal forming part ofthe body, of a knob or handle, of an internally screw threaded washer of thick strong metal, fitted in the back part of such shell, and teats forced from the washer and eX- tending through the shell.

In the accompanying drawings, Figure l is a centralY longitudinal section of a shell forming part of a knob or handle and a washer fitted in the back part of the same and delineated on a large scale. Fig. 2isa perspective view of the shell; and Fig. 3 is a perspective View of the washer detached from the shell, but in. the condition which it has When secured to the shell.

Similar letters of reference designate correspondir g parts in all the gures.

A designates a shell, which forms the rear part of a knob or handle. It is made of sheet `metal, and, as shown, ares'from the back to the front. At the back is au inwardly-turned flange, a.

B designates a Washer, made of thickstrou'g It fits snugly in the back part of the shell A againstthe ilange a. It is secured in place within the shell A by having 4.o teats b punched or struck up and forced through the flange a'of the shell A. These teats may be upset outside the ilange of the shell-like rivets; but the washer will be well secured iu the shell without upsetting the 45 teats. l

` Although the holes a in the iiauge @can adf vantageously be formed by forcing the teats b through the flange, yet these holes c may be formed first, if desirable, with a punch or 5c other tool.

The washer is internally screwithreaded, s'o that the knob or handle may be secured to a. stove or other article by a screw, C.

The front of the knob or handle may consist 55 of a shell of sheet metal secured to the shell A by having its edges lapped over theA adj acent edges vof the shell A.

What I vclaim as my invention, and desire to secure by Letters Patent, is-

The combination of a shell of vsheet metal forming. part with the body of a knob or handle, of an internally-screw-threaded washer of thick strong metal fitted in the back part 'of such shell, and teats forced from the washer 65v and extending through the shell, substantially as specified.
